UNIVERSAL JOINT.

Application filed May 31,

My invention. has to do with universal joints and has for its particular object the pro-vision ot' a simple and economical joint as well as one which'can be easily and quickly assembled.

\Vith the above and other objects in view, my invention consists in the arrangement, combination and construction of the various parts of my improved device, described in the specification, claimed in my claims and shown in the accompanying drawings, in which:

Fig. 1 is a plan view with certain parts broken away or a universal joint illustrating my invention. 7

Fig. 2 is a sectional view taken substantially on line 2-2 of Fig. 1.

I have shown a pair of yokes 5 and 6, the ends of the arms of which are open to receive the arms 7 which extend from the central portion 8 of a conventional Cardan cross. Positioned on each of the arms 7 is a sleeve 9 adapted to provide an end thrust bearing as at 10 for the cross arms. sleeve is provided with a groove 11 for the insertion of a screw driver or other suitable instrument to turn the sleeve in its nut 12. Such a nut is provided for each of the sleeves on the inside of each of the yoke arms, the engagement of sleeve and nut be ing thru the screw threads 18. A pin 14 is provided in each of the yoke arms and ex tends into a slot 15 in each of the nuts 12 so that the nuts are prevented from rotating while rotation of the sleeve in the nut will provide adjustment for the bearing 10 be tween the sleeve and its cross arm.

For the purpose of securing the sleeves and cross arms in the yoke arms, caps 16 are provided. one for each of the yoke arms, said caps being secured to the yoke arms by Each 1927. Serial No. 195,156.

studs 17. When adjusting the sleeves for end thrust wear the studs 17 may be loosened. After theradjustment has been made the studs 17 may be tightened to prevent further turning of the sleeves 9 so as to lose theadustment. Conventional lock washers I 18 may be provided for each oi the studs 17.

It will be obvious that various changes may be made in the arrangement, combination and construction of the various parts of my improved device,without departing from the spirit or my invention and it is my intention to cover by my claims such changes as may be reasonably included within the arms, a nut threaded on the inner end of at the cross arms, positioned in the yoke each sleeve'i o-r adjusting it, means on the end of each sleeve for adjusting it and a pin in each yoke arm extended into its adjacent nut to prevent turning of the nut;
